Kinesiology Ch. 7
True or False All of the wrist and hand muscles are innervated from the radial and median nerves of the brachial plexus.
F
True or False Each finger has three interphalangeal joints while the thumb has only two.
F
True or False Hitting the funny bone is actually a contusion to the humeral nerve.
F
True or False Muscles that are considered to be wrist extensors include the extensor carpi radialis longus, extensor carpi radialis brevis, and extensor carpi radialis.
F
True or False Radial flexion is movement of thumb side of hand toward medial aspect or radial side of forearm.
F
True or False The extensor carpi radialis longus muscle can perform weak extension of the elbow when contracting concentrically.
F
True or False The flexor digitorum superficialis performs its action in the frontal plane.
F
True or False The flexor pollicis longus may be palpated on the posterior surface of the thumb.
F
True or False The median nerve and all of the flexor tendons except for the flexor carpi ulnaris pass through the carpal tunnel.
F
True or False There are eleven muscles that are considered to be "intrinsic" to the hand.
F
True or False "Carpal Tunnel Syndrome" is swelling and inflammation from increased pressure in carpal tunnel that results in decreased function of the median nerve.
T
True or False All of the wrist flexor muscles generally have their origins located on the anteromedial aspect of the proximal forearm and the medial epicondyle of humerus.
T
True or False Mostions of the finger metacarpophalangeal joints include flexion, extension, abduction, and adduction.
T
True or False Motions of the wrist joint include flexion, extension, abduction and adduction.
T
True or False Muscles that are considered to be wrist flexors include the flexor carpi radialis, flexor carpi ulnaris, and palmaris longus.
T
True or False Normally, the wrist has more adduction range of motion that abduction range of motion.
T
True or False Opposition is movement of the thumb across palmar aspect to oppose any or all of the phalanges.
T
True or False The extensor carpi ulnaris and flexor carpi ulnaris are the prime movers in ulnar deviation.
T
True or False The extensor digiti minimi is innervated by the radial nerve (C6, 7,8).
T
True or False The flexor pollicis longus is located lateral with respect to flexor digitorum profundus.
T
True or False The interphalangeal joints may be actively flexed to a greater degree with the wrist in slight extension as opposed to full flexion.
T
True or False The muscles that are considered to be the agonists of phalangeal flexion include flexor difitorum superficialis, flexor digitorum profundus, and flexor pollicis longus.
T
True or False The only muscle involved in extending all of the metacarpophalangeal and interphalangeal joints of the four fingers is the extensor digitorum.
T
True or False The ulnar nerve branching from C8 and T1 provides sensation to the ulnar side of hand, the ulnar one-half of ring finger, and the entire little finger.
T
True or False Ulnar flexion is movement of little finger side of hand toward medial aspect or ulnar side of the forearm.
